Professor Randall Parrish

Current Research Focus
Himalayan tectonic evolution and Neogene erosion, mainly Bhutan, Tibet, India, Burma
The measurement of U isotopes in environmental and biological materials (esp. human urine): assessment of exposure to depleted uranium in military conflicts.
U-Th-Pb geochronology applied to a wide variety of applications using accessory minerals and carbonate, mainly using LA-ICP-MC-MS methods.
Innovations in chemistry and mass spectrometry in U-Th-Pb dating and other isotopic systems, including plasma multicollector mass spectrometry
Accessory minerals in metamorphism: reactions, P-T conditions, and isotopic systematics with applications to the Himalaya
The Neogene rise of the Coast Mountains of western Canada as a contributing cause of Northern Hemisphere Glaciation
Exhumation of ultra high pressure metamorphic rocks and its chronometry
Provenance of sediments and dust and applications to Neogene erosion and climate change
Dating of Quaternary carbonate rocks by high precision U-Pb dating in archaeology, hominid evolution, climate archives
Development of improved biomarkers for Pb exposure in population epidemiology using biological materials and teeth.
